| Jatropha curcas has a high biofuel oil content, which could replace polluting fuels, and has great potential for large scale monoculture cultivation in the conventional system. We explored the occurrence, spatial distribution and the functional response of the main phytophagous species of this plant and their natural enemies to explore the potential for conservative biological control. We began sampling phytophagous species and predators when J. curcas plants were six months old. The most common species of phytophagous insects were nymphs and adults of Empoasca kraemeri, followed by Frankliniella schultzei and Myzus persicae. Among the predators, Ricoseius loxocheles, Iphiseioides zuluagai, Araneidae, larvae and adults of Psyllobora vigintimaculata and... |

| O objetivo foi avaliar o parasitismo de ovos de Heliothis virescens em folhas das cultivares comerciais de algodoeiro de fibra branca (BRS 8H) e colorida (BRS Safira) por Trichogramma exiguum, Trichogramma pretiosum e Trichogramma atopovirilia. Trinta ovos da praga, depositados sobre folhas das respectivas cultivares, foram expostos a cada espécie do parasitóide por 48h, em condições controladas, nas quais foram mantidos até a emergência de seus descendentes. Entre as culturas, obteve-se o maior parasitismo na cultivar BRS 8H. T. atopovirilia e T. exiguum apresentaram maiores porcentagens de parasitismo, seguido por T. pretiosum. Os três parasitóides tiveram viabilidade de parasitismo acima de 90% e razão sexual de 0,79 a 1,0 em ambas as cultivares, mas... |

| Palmistichus elaeisis Delvare and LaSalle (Hymenoptera: Eulophidae) is a gregarious and polyphagous parasitoid mainly of Lepidoptera pupae. The objective of this paper as to study the developent of parasitoid on Bombyx mori L. (Lepidoptera: Bombycidae) pupae exposed to one, nine, 18, 27, 36, 45 or 54 female P. elaeisis, respectively. The females of the parasitoid remained in contact with pupae for 24 hours in glass tubes (14.0 x 2.2 cm), packed in a climatic chamber regulated at 25 ± 2°C, 70 ± 10% relative humidity and photo phase of 12 hours. With the exception of density 1:1 (72.72%), in other densities parasitism was 100%. Adults of P. elaeisis did not emerge from pupae at densities of 1:1 and 9:1, but 100.0% of parasitoid emergence was observed at the... |

| An age-mass structured multi-year tritrophic simulation model of the coffee (Coffea arabica var. mundo novo) - coffee berry borer [Hypothenemus hampei (Ferrari)], borer - three parasitoid system was developed. Three years of extensive plant drymatter data and one year of field data on borer dynamics were collected at Londrina, PR, Brazil. The allometric relationships and parameter for plant drymatter allocation were estimated from the field data, but the parameters for borer and its three parasitoids were summarized from the literature. Initial levels of soil factors (e.g., nitrogen and water) and observed weather data were used to drive the model. The model is largely independent of the field data, yet it simulated the dynamics of plant branching,... |

| The development times and the thermal requirements of Wolbachia-infected and antibiotically cured Trichogramma kaykai Pinto and Stouthamer (Hymenoptera: Trichogrammatidae), using Trichoplusia ni Hübner (Lepidoptera: Noctuidae) eggs, were assessed at four constant temperatures (15, 20, 25, and 30°C), 70 ± 5% RH, photophase 14 h. The knowledge of temperature effects are very important in helping understand the dynamics of desert organisms like T. kaykai that face extreme temperatures during the season. Cured wasps developed faster at higher temperatures (20, 25, and 30°C) than infected wasps. However, infected wasps developed faster at the lowest temperature (15°C) than cured wasps. Developmental times of cured and infected wasps increased from 7.0 and 7.1... |

| Galling insects have developed many strategies to preclude or reduce the attack by natural enemies, such as an increased wall thickness early in the season, and switching to larger and tougher walls later in the maturation stage. In this study, we observed the efficiency of each one of these parameters in reducing mortality of the leaf galling wasp Atrusca caprone Weld (Hymenoptera: Cynipidae), on Quercus turbinella Greene (Fagaceae), during the three months of gall development (June-August). Gall diameter and wall toughness increased from the first to the third month of the study (ANOVA, Diameter: F = 88.73, p < 0.0001; ANOVA, Toughness: F = 26.13, p < 0.0001). However, gall wall thickness increased from June to July, decreasing in August (ANOVA, F... |

| In this study we recorded the occurrence of insect galls, inductors and parasitoids in plants of several physiognomies of Brazilian Cerrado in the Serra dos Pireneus, Goiás State, Brazil. We found 62 morphotypes of gall on 28 botanical families, comprising 44 genera and 51 species. The plant families that showed the greatest richness of galls were Fabaceae, with eight morphotypes, and Styracaceae with six. Styrax pohlii (Styracaceae) was the host plant species with the greatest gall richness, featuring five morphotypes. Most of galls occurred on the leaves (82.6%), 45.1% in vegetation of typical savanna and 35.4% in rocky savanna. Dipteran, Hemipteran and Lepidopteran galls were found, being 50.9% of them induced by Cecidomyiidae (Diptera). Several... |

| Abstract During the samplings described here, Aphidius avenae (=picipes) (Haliday, 1834) was collected. This species has been reported in Chile but has never been studied in terms of its relative abundance and prevalence in central and southern Chile by using classical or molecular methods. The composition of the parasitoid assemblages on several cereal aphid hosts was examined for three seasons in agricultural landscapes. In this note, we describe the prevalence of this parasitoid species in cereal aphids and other aphid hosts and discuss the abundance of this parasitoid compared to other aphid parasitoids and the probable origins of this important aphid parasitoid species in Chile. The results indicate that A. avenae has a low prevalence compared to... |

| El almacenamiento a bajas temperaturas, de 0 a 15ºC, es un método que se usa para prolongar la vida útil de algunas especies de enemigos naturales que se usan en control biológico. En este trabajo se estudió el efecto de la combinación de temperaturas (5, 8, 10 y 25ºC) y periodos de almacenamiento (7, 14 y 21 d) sobre la supervivencia, fecundidad, depredación (alimentación sobre el huésped) y capacidad de vuelo de adultos del parasitoide Catolaccus hunteri Crawford (Hymenoptera: Pteromalidae). Para la evaluación de estos parámetros, una vez que se concluyeron los periodos de almacenaje, los parasitoides se mantuvieron a 25ºC±1ºC, 65±5% H.R. y fotoperiodo 12:12 h L: O. En general todos los parámetros biológicos disminuyeron conforme se incrementó el... |

| Aleiodes Wesmael is the most diverse rogadine genus, with koinobiont endoparasitic development in Lepidoptera caterpillars resulting in mummification of the host remains. Aleiodes japi sp. nov. is described and illustrated. Type specimens of the new species were reared from Physocleora grosica and Ischnopteris sp. (Lepidoptera, Geometridae, Ennominae) larvae. Host larvae were collected on Alchornea triplinervia (Euphorbiaceae) at the Reserva Biológica Municipal da Serra do Japi, Jundiaí, São Paulo, Brazil. This is the second species of circumscriptus/gastritror group described from Brazil. |
